GCC 3.0 bootstrap failure under AIX 4.3

[Robert Boehne <rboehne at ricardo-us dot com>]

Hello,

I'm attempting to bootstrap g++ 3.0 under AIX and I'm running
into a problem that appears to stem from the patch to
mknumeric_limits discussed in this thread:

http://gcc.gnu.org/ml/libstdc++/2001-05/msg00361.html

The bootstrap fails during configuring libstdc++ for
pcc64 saying:

Running configure in multilib subdirs pthread power powerpc ppc64

Cannot run a 64-bit program on a 32-bit machine.
gen-num-limits failed to execute, exiting.
mknumeric_limits failed to execute properly: exiting
gmake[1]: *** [configure-target-libstdc++-v3] Error 1
gmake[1]: Leaving directory `/boreas/build-gcc3'
gmake: *** [bootstrap] Error 2

This failure is after power/ and powerpc/ versions
are configured.  I'm not familiar with libstdc++ source,
but doesn't this patch prevent cross-compiling altogether?

Thanks,

Robert
